Bis(dimethoxyethane-1κ2 O,O′)pentakis(1,1,1,3,3,3-hexafluoropropan-2-olato)-2κ3 O,3κ2 O-μ-hydroxido-1:3κ2 O-μ3-oxido-1:2:3κ3 O-magnesiumdialuminium

The title complex was formed as a partial hydrolysis product of [Mg(dme)3][Al(hfip)4]2 (dme = dimethoxyethane and hfipH = hexafluoroisopropanol), a promising electrolyte salt for magnesium batteries.


The tetrahedral shape of the [AlO
In the extended structure, the hydroxido unit forms an intermolecular O-H� � �F hydrogen bond (Table 1) to the hfip moiety of the OAl(hfip) 3 group.

Synthesis and crystallization
Single crystals of the title compound formed in a partial hydrolysis of the [Mg(dme) 3 ][Al(hfip) 4 ] sample (Pavc ˇnik et al., 2022) that was kept on a watch glass under the layer of perfluorodecaline, upon storage in refrigerator at about 8 � C for a day.The formation of this hydrolysis product could be tentatively described with the following equation: [Mg(dme

Refinement
The crystal data, data collection, and structure refinement details are summarized in Table 2. Hydrogen atoms were refined freely including their isotropic thermal parameters (Cooper et al., 2010).

Special details
Geometry.All esds (except the esd in the dihedral angle between two l.s.planes) are estimated using the full covariance matrix.The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry.An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s.planes.112.11 (7)
